Question

For example I have

*line[30];

I want to allocate a string 81 characters for each pointer. How can I do that and in which way can I access the second string for example to use it in a printf?

Also what about **a, is it an equivalent?

I’m a newbie and this may be an easy question, but I’m eager to learn. Thank you very much!

Answer 1

Below code snippet will help you.

#define MAX_LINES 30
#define MAX_CHARS 81
...
char * line[MAX_LINES];
int i;
for (i = 0; i < MAX_LINES; i++)
{
    line[i] = malloc(sizeof(char) * MAX_CHARS);
}

Use the same for loop for accessing each line. line[1] will access second string (ie line).
